      I came across an article I found interesting so I figured I'd share. It involves a problem I was hitting with yellowing when working with clear plastics. I tend to overshear a bit which causes the yellowing issue when working with optical-grade clear polycarbonate. It looks like a new plasticating system was developed that should help out with yellowing if anyone else is experiencing that issue. It's supposed to stop black spots too but I've never seen that particular issue.
